Product Overview

The Drug-Eluting Stent Coating Spray System is a specialized ultrasonic spraying machine designed for applying drug coatings to stents. Equipped with TMAX’s micro-fine or focused ultrasonic nozzles, it utilizes ultrasonic atomization technology to prepare homogeneous drug coatings on stent surfaces. The system ensures precise drug loading, eliminates coating defects (adhesion, pinholes, etc.), and supports coatings for coronary, peripheral, sinus, and intracranial stents.

TMAX’s spray system employs a proprietary micro-nozzle design with optimized fluid/gas delivery, enabling ultra-precise spray patterns (1–10 mm width) and minimal flow rates. It uniformly coats stents with drug solutions (e.g., rapamycin, paclitaxel in organic solvents), forming dense, defect-free layers. Integrated stent fixtures allow rapid loading/unloading, while an onboard drying module accelerates processing.
